Ho Drawing.

To all whom it may concern:

Be it known thatI, Cmnnns P. MERRY, a citizen of the United States, residing at New Orleans, Louisiana, have invented a new and useful Improvement in Compositions for Facilitating the Fitting of Bearings, of which the following is a specification.

The object of my invention is the production of a composition to be used in the fitting of bearings generally. Its particular characteristics make it highly efficient in the fitting of bearings whose softness renders them easily impregnated by a hard abrasive. It is found that in the use of hard abrasives as emery or glass in the fitting of bearings of softer material that the bearing becomes impregnated with the abrasive which causesundue wear of the shaft operating in the bearixlilg. By the use of my composition this difiic ty is avoided and a rapid and perfect fit ismade possible.

In use it is applied in a similar manner to 'the well known Prussian blue While the bearing is being scraped. By the use of my composition it is not necessary to set the bearings up tightly and allow them to Wear in as the compound effects a perfect fit which is not obtainable by scraping in the usual manner.

My composition consists of a mixture of lime quartz, white lead, zinc, boracic acid and lamp black.

In preparing the composition I prefer to use the ingredients in about the following proportions:

Percent. Lime uartz White ead a 32 Zinc L 12 Boracic acid 7 Lamp black 4 The addition of lamp black gives a Inbricating characteristic to the composition and incidentally color thereto. The lead and zinc form a very eficient carrying body. The boracic acid assists in making the quartz solvent. The quartz which forms an ab Application filed June 8, 1922. Serial No. 565,750.

11 preparin pass it throug a'screen having a number hundred and fifty (150) standard mesh.

I prefer to furnish my composition in a form of powder to be mixed with a quantity of lubricating oil when used.

Having. described my invention what I claim is 1. A composition for facilitating the fit-- ting of bearings comprising a mixture of a mineral abrasive, white lead, zinc and boracic acid.
